[ale] Virtualization recommendations

[Derek Atkins]

IIRC the real-time issues seem to only apply when dealing with actual
POTS hardware.  If you're just doing SIP then it seems to be fine in a
virtual environment.  I've been running asterisk in a VM for well over a
year with very little issue (except that the configuration is b0rked so
right now I only have it set up for outgoing calls -- incoming calls get
forwarded to my mobile from the upstream provider).
